Benefits of upgrading firmware
When you upgrade the firmware on the Rack PDU:
• You obtain the latest bug fixes and performance improvements.
• New features become available for immediate use.
Keeping the firmware versions consistent across your network ensures that all Rack
PDUs support the same features in the same manner.
Firmware files (Rack PDU)
A firmware version consists of two modules: An APC Operating System (AOS) module
and an application module. Each module contains one or more Cyclical Redundancy
Checks (CRCs) to protect its data from corruption during transfer.
The APC Operating System (AOS) and application module files used with the Rack
PDU share the same basic format:
apc_hardware-version_type_firmware-version.bin
• apc: Indicates that this is an APC file.
• hardware-version: hw0x identifies the version of the hardware on which you can
use this binary file.
• type: Identifies whether the file is for the APC Operating System (AOS) or the
application module for the Rack PDU.
• version: The version number of the file.
• bin: Indicates that this is a binary file.
